  28. Wait- some of my answers don't match with what you put. I better go and review the lesson before I submit my test.

    After reviewing the lesson, I got 100! Thanks for posting the answers so kids like me can check and go back through the lesson when we don't match on answers. This tells me what to ask for help on in learning support.
